Here is one: /wrkdirs/usr/ports/editors/openoffice-devel2/work/aoo-4.2.0/main/solver/420/unxfbsdx.pro/inc/osl/diagnose.hxx:65:25: warning: 'osl_detail_ObjectRegistry_getMutex' has C-linkage specified, but returns user-defined type '::osl::Mutex &' which is incompatible with C [-Wreturn-type-c-linkage] In sal/inc/osl/diagnose.hxx, ::osl::Mutex & SAL_CALL osl_detail_ObjectRegistry_getMutex() is declared inside an extern "C" block, so it should have C linkage, but it is returning a reference, which is a C++ thing. The obvious fix would seem to be to move it out of the extern "C" block, but I don't know what to do about the SAL_THROW_EXTERN_C() part of the declaration. Another one is -Woverloaded-virtual which has a number of instances. These are the top three in terms of warning count (due to repeats): main/solver/420/unxfbsdx.pro/inc/cppuhelper/compbase4.hxx:75:31: warning: 'cppu::WeakComponentImplHelper4<com::sun::star::accessibility::XAccessible, com::sun::star::accessibility::XAccessibleContext, com::sun::star::accessibility::XAccessibleEventBroadcaster, com::sun::star::lang::XServiceInfo>::addEventListener' hides overloaded virtual function [-Woverloaded-virtual] main/solver/420/unxfbsdx.pro/inc/cppuhelper/compbase4.hxx:77:31: warning: 'cppu::WeakComponentImplHelper4<com::sun::star::accessibility::XAccessible, com::sun::star::accessibility::XAccessibleContext, com::sun::star::accessibility::XAccessibleEventBroadcaster, com::sun::star::lang::XServiceInfo>::removeEventListener' hides overloaded virtual function [-Woverloaded-virtual] main/solver/420/unxfbsdx.pro/inc/canvas/base/graphicdevicebase.hxx:145:31: warning: 'canvas::GraphicDeviceBase<canvas::BaseMutexHelper<cppu::WeakComponentImplHelper9<com::sun::star::rendering::XSpriteCanvas, com::sun::star::rendering::XIntegerBitmap, com::sun::star::rendering::XGraphicDevice, com::sun::star::lang::XMultiServiceFactory, com::sun::star::rendering::XBufferController, com::sun::star::awt::XWindowListener, com::sun::star::util::XUpdatable, com::sun::star::beans::XPropertySet, com::sun::star::lang::XServiceName> >, vclcanvas::SpriteDeviceHelper, vclcanvas::tools::LocalGuard, cppu::OWeakObject>::disposing' hides overloaded virtual function [-Woverloaded-virtual] I'm not sure if there is really a problem here or if the warning is harmless. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@openoffice.apache.org For additional commands, e-mail: dev-h...@openoffice.apache.org
